## Textual Inversion fine-tuning example for SDXL

```sh
export MODEL_NAME="stabilityai/stable-diffusion-xl-base-1.0"
export DATA_DIR="./cat"

accelerate launch textual_inversion_sdxl.py \
  --pretrained_model_name_or_path=$MODEL_NAME \
  --train_data_dir=$DATA_DIR \
  --learnable_property="object" \
  --placeholder_token="<cat-toy>" \
  --initializer_token="toy" \
  --mixed_precision="bf16" \
  --resolution=768 \
  --train_batch_size=1 \
  --gradient_accumulation_steps=4 \
  --max_train_steps=500 \
  --learning_rate=5.0e-04 \
  --scale_lr \
  --lr_scheduler="constant" \
  --lr_warmup_steps=0 \
  --save_as_full_pipeline \
  --output_dir="./textual_inversion_cat_sdxl"
```

Training of both text encoders is supported.

### Inference Example

Once you have trained a model using above command, the inference can be done simply using the `StableDiffusionXLPipeline`.
Make sure to include the `placeholder_token` in your prompt.

```python
from diffusers import StableDiffusionXLPipeline
import torch

model_id = "./textual_inversion_cat_sdxl"
pipe = StableDiffusionXLPipeline.from_pretrained(model_id,torch_dtype=torch.float16).to("cuda")

prompt = "A <cat-toy> backpack"

image = pipe(prompt, num_inference_steps=50, guidance_scale=7.5).images[0]
image.save("cat-backpack.png")

image = pipe(prompt="", prompt_2=prompt, num_inference_steps=50, guidance_scale=7.5).images[0]
image.save("cat-backpack-prompt_2.png")
```
